Abstract

A yarn sluice for sealing a pressurized yarn treating chamber in which a traveling yarn is thermally treated, comprises yarn guide elements in the region of a yarn inlet and outlet openings of the treating chamber forming a yarn guide channel sealed by the traveling yarn during operation. At least one of the guide elements is positionable for adaptation to the mean thickness of the traveling yarn in various predetermined positions. Means is provided for temporary adaptation of the yarn guide channel to yarn defects. At least one of the guide elements (26, 27) is steplessly adjustably mounted for adaption to the mean thickness of the traveling yarn (14). A sealing element (28), which can be placed on the first and the second yarn guide element (26, 27), extends along the yarn guide channel (25), for closing it and for reacting resiliently to defects in the traveling yarn (14).
